lVlLLlAM PLOTTS, OF MCDONALD, PENNSYLVANIA.

BAlLER.

SPEGIIFJDUATION forming part of Letters Patent No. 64=O,d14, dated January 2, 1900.

Application filed January 29, 1896. Serial No. 577,245. (No model-l To (all whom, it may concern.-

Be it known that I, WILLIAM Pnorrs, a resident of McDonald, in the county of l/Vashington and State of Pennsylvania, have invented a new and useful Improvement in Bailers; and it do hereby declare the following to be a full, clear, and exact description thereof.

Myinvention relates to bailers for oil-wells and other purposes for which it maybe found applicable.

My invention relates more particularly to certain improvements in the bailer set forth in Letters Patent No. 496,323, granted to me April 25, 1893, the object of my present invention being to provide the opening of the bailer with a sliding cover, which will begin to open before the bailer reaches the bottom of the well.

To enable others skilled in the art tomake and use my invention, 1 will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a front view of the bailer, showing the cover raised. Fig. 2 is a like view, showing the cover lowered. Fig. 3 is a section on the line 3 3, Fig. 1. Fig. i is a section on line et a, Fig. 2; and Fig. 5 is a detail view of the hinge connection of the cover.

Like letters indicate like parts in each of the figures.

As the invention only relates to the lower end of the bailer I have not deemed it necessary to illustrate and describe the upper parts, which are set forth in said Letters Patent.

The body CL of the bailer is cut away in the front to form the slightly-indented portion 1). An opening 0 is formed in this indented portion I), said opening being provided with the interior sliding cover (Z. This cover (1 is connected to the band 6 by the bolt f. The band 6 extends across the front or indented portion 7) of the body a of the bailer and has the arms 6 depending therefrom and connected to the weight 7t. The weight h may be of any suitable shape; but I prefer to employ a crescent-shaped weight, such as is set forth and claimed in an application for Letters Patent filed by me of even date herewith, Serial No.

577,2-il. The band 6 has the seat i formed thereon, through which the bolt f passes. The inner end of the bolt fis bifurcated, a pin it passing through said end, and a lugZ on the cover (Z secures said cover to said bolt. This connection permits said cover to swing inwardly, as shown in dotted lines, Fig. 3. A spring at is interposed between a shoulder 1'. at the inner end of the seat t' and the headf of the bolt. This spring tends to retain the cover (Z normally in its vertical position, shown in full lines, Fig. 3.

The operation of the bailer is as follows: hen lowered into the well, the weight of the column of fluid in the well forces the cover (Z to swing to the position shown in dotted lines, Fig. 3, and admits the sediment into the bailer, even though the weight 71/ has not reached the bottom of the well. As the bailer descends to the bottom of the well it is thus gradually opened until the weight striking said bottom the cover is raised to the position shown in full lines, Fig. 3, and the opening is entirely opened. When the bailer is raised the weight will lower the cover and close the opening to prevent the escape of the contents.

That I claim as my invention, and desire to secure by Letters Patent, is-- 1. A bailer having an opening formed therein, a cover for said opening, said cover being adapted both to slide vertically beyond the opening and swing inwardly, substantially as set forth.

2. A bailer having an opening formed therein, a cover for said opening, a weight, arms extending up from said weight, a band connecting said arms, said cover having a hinge connection with said band, substantially as set forth.

8. A bailer having an opening formed therein, a cover for said opening, a weight, arms extending up from said weight, a band connecting said arms, a bolt passing through said band and having a hinge connection with said cover, and a spring for holding said cover normally in a vertical position, substantially as set forth.

t. A bailer having an opening formed therein, a cover for said opening, a weight,

arms extending up from said Weight, a band I11 testimony whereof I, the said WILLIAM connecting said arms, said band having a PLOTTS have hereunto set my hand. seat therein, a bolt passing through said seat, said cover being hinged to the inner end of 5 said bolt, and a spring interposed between a WVitnesses:

shoulder in said seat and the head of said ROBT. D. TOTTEN, bolt, substantially as set forth. ROBERT C. TOTTEN.
